'- UNITED STATES THOMAS .T MALO, OF HAMMOND, NDIANA DECARBONIZER FORINTERNAL-COMBUSTION ENGINES Application led .Tune 19,

This invention relatos to a decarbonizer for internal combustion enginesand more particularly to a device for supplying moistened air for use inthe cylinders ot the engine.

An important object of the invention is the provision in a device ofthis character of a construction permitting proportional mixture withmoistenedair or air which has not been moistened and of gases or vaporswithdrawn from the c1ankcase of the engine.

A further object of the invention is to provide a device of thischaracter which may he completely controlled in its operations toregulate the proportions of moistened and unmoistened air to the fumesor vapors withdrawn from the engine crank-case.

A still further object of the invention is to provide a constructionpermitting the use of a substance such as a penetrating oil in themoistening chamber which will add to the value of the mixture deliveredto the cylinders as an explosive compound and which will assist in theremoval of carbon deposits from the .Walls of the cylinders and valves othe engine.

A still further object of the invention is the provision of a device ofthis character Which may be readily and cheaply produced, durable andefficient in service and a general improvernent in the art.

These and other objects l attain by the construction shown in theaccompanying drawing, wherein for the purpose of illustrau tion is showna preferred embodiment of my invention and wherein Figure 1 is avertical sectional l view through a decarbonizer for internal combustionengines constructed in accordance with my invention;

Figure 2 is a View similar to that of Figure 1 and at right anglesthereto;

Figure 3 is a section on the line 3--3 of Figure 1.

Referring now more particularly to the drawing, the numeral 10designates a cylindrical 'and preferably transparent side wall which, atits ends, engages upper and lower caps 11 and 12 through gaskets 13.vl`he cpper cap preferably has means 14 whereby it may be securedto asupport. Depending 1928. Serial No. 286,593.

from the upper cap is a tubular connecting bar 15, the lower end ofwhich is sealed, .as at 16, and is directed through an opening l? formedin the bottom cap 12. A nut 18 engaging the under surface of the bottomcapy a tubular boss 22 produced upon the latter at! its center.Retaining nuts 23 lock the pipe in position and the interior of the pipeis threaded, as l at 24,' for the reception of a valve screw 25.,

The boss and pipe are perforated at a piaf rality of points by minuteports 26 controlled by ythis valve and the boss has arising. theren froma spring finger 2T. engaging. the head 28 of the screw valve. vThetubular connecting bar l5 has a vent 29 opening to the interior of thecasing produced by the caps and cylindrical wall at the upper endthereof and beiew the level of liquids hereinafter to be described whichare placed in this casing. v

The upper cap 11 has further opening therethrough a lport 30, the wallof which is interiorly threaded, as -at 31, for the reception of ascrevir valve 32. This port is refu erably in the form of an insertedvalve ody and has its wall perforated at a plurality of points, asindicated at 33, by minute ports which are controlled by the valve screw32.

@his valve screw is held in adjusted positions in a manner similar tothe valve screw 25.

these fittings each having the bores 41 plugged, as indicated at 42,with a plug having a minute port 43 formed therein. Each fitting furtherhas its outer end in the form of a coupling 44 to engage one end of aconduit 45 connecting the fittings` The upper cap may belikewiseprovided with a removable plug through which liquids may beintroduced to the casing.

In use of the device, after its installation, it is partially filledwith water and a light penetrating oil `which is preferablycharacterized by the fact that it is readily miseible in water. l

In the operation of the engine, it will be obvio-us that suction will becreatedin the upper end of the casing and by this suction, air-Will be.drawn through the port 31 and vents 29 iid vapors will be drawn from thebase of the engine through the fittings 38 and 39. Theport 31 hasassociated therewith a tube 45 by means of which air passingtherethrough is discharged into the casing at the lower end thereof. Itwill, therefore, be obvious that a mixture of moistened air andunmoistened air and vapors drawn from the base of the engine will bedrawn through the conduit 37 to the intake manifold. The proportions ofthese vapors to one another may be very closely regulated by adjustmentof the valves 25 and 32, and it will be obvious,

if sufficient air is admitted through these valves, the amount of vaporsdrawn 4from the base of the engine will be relatively low while, if theamount of air permitted to pass through these valves is reduced, theproportion of the amount of vapors will be increased. It will also beobvious that the proportionate amounts of moistened and unmoistened airmay be closely regulated by regulation of the valves 25 and 32, with theresult that a perfect balance of these elements is obtainable. The airwhich enters through the port 3l and tube 45, since it passes upwardlythrough the water and oil, will agitate the same so that after a shortperiod of operation, these elements will be thoroughly mixed and airpassing therethrough will contain moisture derived from both and acertain percentage of both. This air intermingling with the streamarising from the carbureter will serve to break up this air stream andany liquefied particles carried thereby and thoroughly intermingletherewith. The penetrating oil, when delivered to the cylinders, willact upon the carbon deposits therein to soften and loosen the same, sothat they may be released by the shock of an explosion land dischargedthrough the exhaust pipe.

It has been found in tests of apparatus of this character that when aproper balance of the mixture is obtained, the low speed controladjusting screw with which most carbureters are now supplied may becompletely removed and a perfect idling operation obtained. It has alsobeen found that with a properly regulated mixture, the combustion is socomplete that the gases exhausted from the engine are substantiallynon-poisonous.

Since the construction hereinbefore set forth is capable of a certainrange of change and modification without materially departing from thespirit of the invention, I do not limit myself te such specificstructure except as hereinafter claimed.
